Ladder Programming Precautions
Section 3-4
LR Area Allocation for
Multi-level Mode
• Link #0
• Link #1
Example 1:
An existing C1000H/C2000H PLC is set to multi-level mode operation, link #0,
node address 5, and 32 Link Relay bits/Unit, so LR 10 and LR 11 are used as
the transfer area.
In the replacement CVM1/CV-series PLC, use CIO 1010 and CIO 1011 as the
transfer area.
